Abstract
PURPOSE: To supply effective power through A.C. reactor from power source to inverter so that a fixed reactive power is generated by providing a phase regulator to regulate the phase difference of output voltage of self-exciting inverter on the basis of the voltage phase of power sources.
CONSTITUTION: The power source 1 is connected through the A.C. reactor 2 the inverter device 4, and the gate circut 42 is given the output of the phase regulating circuit 40 which puts out through the differential circuit 43 by comparing the voltaga from the power source with the control voltage Ec by the comparator 24 throught the transformer 11, whereby obtaining six phase from three phase. On the other hand, the refernce reactive power Qr and the detected reactive power Qf are added by the summing operational unit 27 through the polarity converter 24 to obtain the control voltage Ec. Thus, by obtaining a power corresponding to power loss in the inverter 4 directly from the power source, the need for D.C. input circuit is eliminated and thus the miniaturization of the device can be attained
